After the first episode, I was completely absorbed in this drama. My expectations were very high after the first episode (which is already a mistake), but I couldn't help it. This kdrama was one of the best kdramas I've ever seen, though not my favorite, very griping and mind-provoking. This definitely will have you at the edge of ur seat. I'm gonna state right off the bat that this is a heavy drama, as in not one I'd really rewatch. Maybe I will at some point, but definitely no time soon. And not because this drama isn't good, because I think this drama is excellent (I watched it in two days), but the themes are so serious and I'm more of a light-hearted gal myself. The only true issue I have with this drama is the finale, it was very confusing and not very satisfying. The ending felt lazy and rushed, and I was left thinking "that's it"? I originally decided to watch this because of Song Hye Kyo, but her character wasn't very likable to me. Then I saw Kim Bum was in this, and I knew I had to watch. But honestly, Jo In Sung made this drama for me, and now I want to watch everything with him in it. His laugh kills me lmao, but that's neither here nor there. The acting and cast was phenomenal. The ost was breathtaking. This drama was beautiful. In Sung's character, Oh Soo, is a gambler/con-man who shares the same name as Oh Yeong's brother. Oh Yeong is blind and believes there's no one she can trust, and Oh Soo is mistaken as Oh Yeong's brother. This case of mistaken identity happens at the most opportune moment, because Oh Soo has gotten himself into some serious trouble, and he has a large debt to pay or else he'll be killed. Oh Yeong's family just happens to be rich, so Oh Soo pretends to be her long lost brother so he can get the money to pay off his debt. Gaining Oh Yeong's trust is much harder than he thought, and in the process of doing so he falls in love with her. It's really a beautiful story. Only reason why I didn't rate it higher is because of the finale, I was just left so unsatisfied and had a lot of questions that never got answered. I really did enjoy this drama though, and I'd definitely recommend it, especially to those looking for a serious, different type of love story (because this one's definitely not typical).
